Chondroitin and osteoarthritis
3 trials of chondroitin alone in patients with osteoarthritis found limited evidence that chondroitin improved
symptoms more than placebo.
However, the benefit seen with glucosamine was also seen in a study of a combination of glucosamine and chondroitin when treatment over 6 months benefited those with mild to moderate OA but not those with severe OA
.
